... so it's time for a new update ;-)
GCC 4.8 is still in its stage 3 development phase, so Zorry will send out the patches to the GCC development community when this phase is done. For Gentoo hardened itself, we now support all architectures except for IA64 (which never had SSP).
Full uclibc support is now in place for amd64, i686, mips32r2: not only is their technological support ok, but stages are now also automatically built to support installations through the regular installation instructions. The next target to get stages automatically built for is armv7a.
Kernel and grSecurity/PaX
Stabilization on 3.6.x is still showing some difficulties. Until those are resolved, we're still stable in 3.5.4. We have a couple of panics in some odd cases, but these will need to be resolved before we can stabilize further.
glibc-2.16 will also drop the declarations for PT_PAX (in elf.h) and the binutils will also not cover PT_PAX phdr anymore. So, we will standardize fully on xattr-based PaX flags. This will get some proper focus in the next period to ensure this is done correctly. Most work on this support is focusing on communication towards users and the pax-utils eclass support.
There was some confusion if the tmpfs-xattr patch would or would not properly restrict access, but it looks like the PaX patch on mm/shmem.c was based upon the Gentoo patch and enhanced with the needed restrictions, so we can just keep the PaX code.
On USE="pax_kernel", which should enable some updates on userland utilities when applications are run under a PaX enabled kernel, prometheanfire tried to get this as a global USE flag (as many applications might eventually want to get a trigger on it). However, due to some confusion on the meaning of the USE flag, and potential need to depend on additional tools, we're going to stick with a local flag for now.
schmitt953 will help in the testing and possible development of SELinux policies for Samba 4.
Furthermore, the userspace utilities have been stabilized (except for the setools-3.3.7-r5+ due to some swig problems, but those have been worked around in setools-3.3.7-r6). Also, the rev8 policies are in the tree and no big problems were reported on them. They are currently still \~arch, but will be stabilized in the next few days. A new rev9 release will be pushed to the hardened-dev overlay soon as well.
nvidia is unmasked for the hardened profiles, but still has X and tools USE flags masked, and is only supported on kernels 3.0.x and higher.
Also, the hardened/linux/uclibc/arm/armv7a profile is now available as a development profile. Profiles will be updated as the architectures for ARM are getting supported, so expect more in the next month.
We were waiting for kernel 3.7, which just got released, so we can now start integrating this further. Expect more updates by next meeting.
For SELinux, some information on USE="unconfined" is added to the SELinux handbook. Blueness will also start documenting the xattr pax stuff.
